Using a `<TextView>` to input text is generally an error, you should be
using `<EditText>` instead.  `EditText` is a subclass of `TextView`, and
some of the editing support is provided by `TextView`, so it's possible
to set some input-related properties on a `TextView`. However, using a
`TextView` along with input attributes is usually a cut & paste error.
To input text you should be using `<EditText>`.

This check also checks subclasses of `TextView`, such as `Button` and
`CheckBox`, since these have the same issue: they should not be used
with editable attributes.

(##) Suppressing

You can suppress false positives using one of the following mechanisms:

* Adding the suppression attribute `tools:ignore="TextViewEdits"` on
  the problematic XML element (or one of its enclosing elements). You
  may also need to add the following namespace declaration on the root
  element in the XML file if it's not already there:
  `xmlns:tools="http://schemas.android.com/tools"`.

  ```xml
  &lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;TextView xmlns:tools="http://schemas.android.com/tools"
      tools:ignore="TextViewEdits" ...&gt;
    ...
  &lt;/TextView&gt;
  ```

* Using a special `lint.xml` file in the source tree which turns off
  the check in that folder and any sub folder. A simple file might look
  like this:
  ```xml
  &lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;lint&gt;
      &lt;issue id="TextViewEdits" severity="ignore" /&gt;
  &lt;/lint&gt;
  ```
  Instead of `ignore` you can also change the severity here, for
  example from `error` to `warning`. You can find additional
  documentation on how to filter issues by path, regular expression and
  so on
  [here](https://googlesamples.github.io/android-custom-lint-rules/usage/lintxml.md.html).

* In Gradle projects, using the DSL syntax to configure lint. For
  example, you can use something like
  ```gradle
  lintOptions {
      disable 'TextViewEdits'
  }
  ```
  In Android projects this should be nested inside an `android { }`
  block.

* For manual invocations of `lint`, using the `--ignore` flag:
  ```
  $ lint --ignore TextViewEdits ...`
  ```

* Last, but not least, using baselines, as discussed
  [here](https://googlesamples.github.io/android-custom-lint-rules/usage/baselines.md.html).
